Spring Cloud Gateway не работает с DiscoveryClientRouteDefinitionLocator ⇐ JAVA

[Anonymous]

Я работал с облачным шлюзом Spring, когда использовал статичные маршруты, подобные этому (он отлично работает):
@Bean
RouteLocator routeLocator(RouteLocatorBuilder builder) {
return builder.routes()
.route((r) -> r.path("/customers/**").uri("http://localhost:8081/"))
.route((r) -> r.path("/products/**").uri("http://localhost:8082/"))
.build();
}

Но когда я хочу использовать динамические маршруты с DiscoveryClientRouteDefinitionLocator, это не работает
Вот моя функция:
@Bean
DiscoveryClientRouteDefinitionLocator definitionLocator(
ReactiveDiscoveryClient rdc,
DiscoveryLocatorProperties properties) {
return new DiscoveryClientRouteDefinitionLocator(rdc, properties);
}

А это мое приложение.Свойства:
server.port=8888
spring.application.name=gateway-service
spring.cloud.discovery.enabled=true

когда я вызываю этот uri http://localhost:8888/PRODUCT-SERVICE/products, я получаю:
Whitelabel Error Page
This application has no configured error view, so you are seeing this as a fallback.
